Safeguarding Software Testing from Data Poisoning

Data poisoning has recently gained significant attention in the news due to its negative impact on machine learning (ML) and artificial intelligence (AI) systems. However, data poisoning is not a new phenomenon and has been a concern in various domains, including software testing. In the context of software testing, data poisoning refers to the deliberate manipulation or contamination of data used in the testing process, with the aim of compromising the accuracy and effectiveness of the tests. 

For example, consider a scenario where a malicious actor intentionally modifies the input data used in a software's login functionality test cases. They may introduce invalid or edge case inputs, such as extremely long usernames or passwords containing special characters, to test the system's resilience against unexpected or malicious inputs. Another example could be the manipulation of test environment variables, such as changing the database connection string to point to a corrupted or tampered database, leading to incorrect test results and potentially hiding critical defects.

What is Data Poisoning?

Data poisoning involves introducing malicious, misleading, or incorrect data into the testing dataset to disrupt the testing process and produce misleading results. It can occur at various stages of the testing lifecycle, from test case generation to test execution and result analysis. There are several types of data poisoning that can affect software testing:

• Input Manipulation: This involves modifying the input data used in test cases to introduce edge cases, invalid inputs, or malformed data. The goal is to test the software's ability to handle unexpected or malicious inputs gracefully.
• Test Data Corruption: In this type of data poisoning, the test data itself is corrupted or tampered with. This can include modifying existing test data, injecting false data, or deleting critical data points. The aim is to disrupt the testing process and produce misleading results.
• Test Environment Manipulation: Data poisoning can also target the test environment by altering configuration settings, modifying environment variables, or introducing external dependencies that affect the behavior of the software under test.
• Result Manipulation: In some cases, data poisoning may involve tampering with the test results themselves. This can include modifying log files, altering test reports, or manipulating the pass/fail criteria to hide defects or falsely indicate successful test runs.

Impact of Data Poisoning on Software Testing

Data poisoning can have severe consequences on the software testing process and the overall quality of the software being developed. Some of the key impacts include:

• False Positives and False Negatives: Poisoned data can lead to incorrect test results, causing false positives (tests passing when they should fail) or false negatives (tests failing when they should pass). This can mislead testers and developers, leading to the release of software with hidden defects or the unnecessary allocation of resources to fix non-existent issues.
• Reduced Test Coverage: Data poisoning can affect the thoroughness of the testing process by limiting the scope of test cases or skipping critical test scenarios. This can result in inadequate test coverage, leaving portions of the software untested and potentially harboring defects.
• Wasted Time and Resources: Dealing with poisoned data can be time-consuming and resource intensive. Testers may spend significant effort investigating and resolving issues caused by manipulated data, diverting their attention from other important testing tasks. This can lead to project delays and increased costs.
• Compromised Software Quality: If data poisoning goes undetected, it can lead to the release of software with hidden defects or vulnerabilities. This can have severe consequences, such as system failures, data breaches, or compromised user experience, damaging the reputation of the software and the organization.

Detecting Data Poisoning

Detecting data poisoning is crucial to mitigate its impact on software testing. Here are some techniques and approaches to identify poisoned data:

• Data Validation: Implementing robust data validation mechanisms can help identify anomalies or inconsistencies in the test data. This includes validating input formats, ranges, and constraints to ensure data integrity. Any deviations from the expected data patterns can indicate potential poisoning.
• Statistical Analysis: Applying statistical techniques to analyze test data can help detect outliers or unusual patterns. Techniques such as data profiling, distribution analysis, and anomaly detection algorithms can identify data points that deviate significantly from the norm, indicating possible poisoning.
• Data Provenance Tracking: Maintaining a record of the origin and lineage of test data can help trace the source of poisoned data. By tracking data provenance, testers can identify the points of data manipulation or corruption and take appropriate actions to rectify the issue.
• Data Integrity Checks: Implementing data integrity checks, such as checksums or digital signatures, can help detect unauthorized modifications to test data. Any discrepancies between the original and the current data can indicate tampering or poisoning.
• Monitoring and Logging: Establishing comprehensive monitoring and logging mechanisms can help detect suspicious activities or unauthorized access to test data. Monitoring access logs, system events, and data modifications can provide insights into potential data poisoning attempts.

Preventing Data Poisoning

Prevention is key to safeguarding the software testing process from data poisoning. Here are some strategies and best practices to prevent data poisoning:

• Access Control and Authentication: Implementing strict access control measures and authentication mechanisms can prevent unauthorized individuals from accessing or modifying test data. This includes role-based access control, multi-factor authentication, and secure password policies.
• Data Encryption: Encrypting sensitive test data both at rest and in transit can protect it from unauthorized access or tampering. Encryption ensures that even if data is intercepted or stolen, it remains unreadable without the proper decryption keys.
• Data Backup and Version Control: Regularly backing up test data and maintaining version control can help recover from data poisoning incidents. By having multiple versions of the test data, testers can revert to a clean state if poisoning is detected, minimizing the impact on the testing process.
• Input Validation and Sanitization: Implementing robust input validation and sanitization techniques can prevent the introduction of malicious or invalid data into the testing process. This includes validating and sanitizing user inputs, external data sources, and test case parameters to ensure data integrity.
• Security Testing: Incorporating security testing practices, such as penetration testing and vulnerability assessments, can help identify and address potential entry points for data poisoning. By proactively identifying and fixing security vulnerabilities, the risk of data poisoning can be reduced.
• Employee Training and Awareness: Educating and training employees involved in the software testing process about data poisoning risks and best practices can help prevent unintentional or malicious data manipulation. Raising awareness about the importance of data integrity and the consequences of data poisoning can foster a culture of security and vigilance.

Overcoming Data Poisoning Challenges

Despite the best efforts to detect and prevent data poisoning, challenges may still arise. Here are some strategies to overcome data poisoning challenges:

• Incident Response Plan: Developing and implementing a well-defined incident response plan can help quickly identify, contain, and recover from data poisoning incidents. The plan should outline the steps to be taken, the roles and responsibilities of team members, and the communication channels to be used during an incident.
• Data Cleansing and Validation: If data poisoning is detected, it is crucial to cleanse and validate the affected data. This involves identifying and removing the poisoned data points, verifying the integrity of the remaining data, and re-running the affected test cases with clean data.
• Root Cause Analysis: Conducting a thorough root cause analysis can help identify the underlying factors that led to the data poisoning incident. By understanding the root cause, organizations can implement targeted measures to prevent similar incidents in the future.
• Continuous Monitoring and Improvement: Establishing a continuous monitoring and improvement process can help detect and respond to data poisoning incidents more effectively. This involves regularly reviewing and updating detection and prevention mechanisms, analyzing incident trends, and incorporating lessons learned into the testing process.
• Collaboration and Information Sharing: Fostering collaboration and information sharing among software testing teams, security experts, and industry peers can help stay informed about emerging data poisoning techniques and best practices. Sharing knowledge and experiences can collectively enhance resilience against data poisoning threats.

Recipe for Disaster: The 'Don'ts' of Bug Reporting with a Dash of Humor

Welcome to the quirky kitchen of bug reporting, where the secret sauce is in the details and the main ingredient is clarity. Let's ensure your bug report isn't the equivalent of unseasoned dal—bland and unhelpful.

Vague Descriptions: The "Something's Wrong" Syndrome

Ever stumbled upon a bug report that simply states, "It's kaput"? That's as helpful as a chef shouting, "It's not tasty!" in the middle of a bustling kitchen. What's not tasty? The soup? The curry? A good bug report should be like a well-written recipe, with every ingredient and step laid out for a perfect replication of the dish—or in this case, the bug.

The Dance of Reproduction Steps

Trying to fix a bug without reproduction steps is like trying to bake a cake without a recipe. Developers need the full list of ingredients and the baking time to whip up a solution. The more precise your steps, the less likely they'll end up with a deflated cake—or an unfixed bug.

The Environment Puzzle

Saying a bug occurred "on my computer" is as vague as a food critic saying a dish was "good." Was it the spices? The texture? Similarly, was the bug on Windows, macOS, or Linux? Bugs can be finicky eaters, feasting on some systems while ignoring others. Provide a full menu of the environment details to help developers serve up a fix.

Clear Communication: Avoiding the Grammar Gremlins

A bug report with typos and grammatical errors is like a recipe with missing steps. Will your soufflé rise to the occasion, or will it flop? Keep your writing as clean and organized as a chef's prep area. And remember, a screenshot or a video is worth a thousand words—or in this case, a thousand lines of code.

Emotional Baggage: Keep It Checked

It's natural to get steamed up when you hit a bug, but remember, a bug report is not a place to vent. Keep the tone as cool as a cucumber raita. Stick to the facts, and leave the spicy outbursts for your biryani.

Feature Requests in Disguise

A feature request masquerading as a bug is like mistaking cardamom for cumin—they're both spices, but they belong in different dishes. Keep your feature requests and bug reports in separate containers to avoid flavor confusion in the development kitchen.

The Ripple Effect of Poor Reporting

A vague or incomplete bug report can send developers on a wild goose chase, much like sending someone to the market with a shopping list that just says "stuff." Be as specific as a meticulous grocery list, and you'll save everyone a lot of thyme (pun intended).

Conclusion: Serving Up Bug Reports with a Side of Precision

Imagine if writing bug reports were like hosting a cooking show. You'd want your audience (the developers) to follow each step with ease, leading to a perfectly 'baked' solution. While our kitchen (the development environment) might not appreciate literal sprinkles of humor in the 'dough' (the bug reports), our blog can certainly enjoy a light-hearted garnish.

So, as we wrap up our culinary journey through the world of bug reporting, remember: the essence of a great dish lies in its recipe. By avoiding the common pitfalls of vagueness, missing steps, and emotional overtones, your bug reports can be as clear and effective as a chef's prized recipe. Your goal is to present the problem with such precision that developers are guided to a solution as smoothly as a knife through soft butter.

With meticulous attention to detail—and perhaps a cheeky smile as you write—you'll help ensure a smooth and efficient path to a high-quality software product. After all, a well-crafted bug report, much like a well-executed dish, is a thing of beauty that brings satisfaction to all involved. Here's to making the development process not just productive, but also a tad more delightful.

Unraveling the TSO500 Workflow: A Deep Dive into TSO500 Workflow Verification

As a software tester in the genomic healthcare technology field, my responsibility is to ensure the smooth functioning of the TruSight Oncology 500 (TSO500) workflow. This involves overseeing the journey of genetic data from the initial sample processing to the generation of comprehensive health reports, using pre-existing sequencing data. My goal is to clarify the process and highlight the critical steps, particularly the seamless integration of data into the Pierian system.

The Initial Phase: Accessioning and Plasma Batch Creation

The process begins with "accessioning," where each blood sample is meticulously cataloged with a unique identifier. This step is akin to assigning a library card to every book, ensuring each sample can be tracked throughout its journey. Although I work with pre-existing sequencing data, I simulate this step to maintain the integrity of the workflow. Following accessioning, we proceed to create plasma batches. While the lab's capacity allows for up to 192 samples in a single run, my testing typically involves 2 to 4 batches. This scaled-down approach enables me to concentrate on the system's efficiency and accuracy in a more controlled environment.

The Role of DRAGEN: A Black Box in the Workflow

DRAGEN (Dynamic Read Analysis for GENomics) is a key component in the analysis of genetic data, known for its speed and accuracy. However, as a software tester, I do not verify the data analysis within DRAGEN. Instead, my role is to ensure that the data reaches the Pierian system correctly. DRAGEN remains a black box to us, meaning we trust the analysis conducted by DRAGEN without direct verification.

Ensuring Data Integrity and Workflow Efficiency

My primary focus is on the following stages:

• Data Analysis: While I don't verify the data analysis within DRAGEN, I monitor the workflow to ensure that the data is being processed and sent out correctly.
• Data Transfer: A critical part of my role is to confirm the successful transfer of data from the DRAGEN platform to the Pierian Clinical Genomics Workspace, maintaining the integrity of the genetic information.
• 
  Report Generation: I evaluate the Pierian platform's ability to produce comprehensive and actionable health reports from the analyzed data.

Integrating Comprehensive Insights: Beyond TSO500

Once the Pierian report is finalized, it is sent to our order management system, where it is merged with other test reports, such as AR-v7 or DefineMBC. These additional tests provide a broader view of the patient's genomic profile, enhancing the personalized care approach.

AR-v7 is a critical test for metastatic prostate cancer, indicating resistance to specific treatments.

DefineMBC offers a comprehensive profile of metastatic breast cancer, analyzing circulating tumor cells (CTCs) and cell-free DNA (cfDNA) to detect genomic alterations that guide personalized treatment strategies.

Conclusion

My role in testing the TSO500 workflow is crucial for ensuring the workflow's accuracy and reliability. By monitoring each step and confirming seamless integration with PierianDx, we help ensure that the platform delivers clinically actionable insights essential for personalized patient care. This blog post aims to provide a clear understanding of the complex process of turning DNA data into a health report from a software tester's perspective, emphasizing the operational side of the workflow and the importance of data integrity in the overall process.

The Essentials of Lean Testing: Streamlining Software Quality and Efficiency

In the dynamic realm of software development, the importance of efficiency and quality cannot be overstated. This is where Lean Testing comes into play, a methodology that enhances the testing process by applying Lean manufacturing principles to software testing and verification. It aims to streamline testing by eliminating unnecessary steps, reducing waste, and focusing on value-adding activities. The core idea is to make the testing process more efficient and effective by only doing what is necessary to ensure the product meets customer needs and expectations.

The Origin of Lean Testing

Lean Testing draws inspiration from Lean manufacturing principles, which were first developed in the Toyota Production System. These principles aimed to optimize production by minimizing waste and maximizing productivity. Over time, the concept of Lean was adapted to software development, giving rise to methodologies like Agile, and eventually extending to the testing process itself. The transition to Lean Testing was driven by the desire to apply the same efficiency-focused mindset to the testing of software products.

Principles of Lean Testing

The principles of Lean Testing are derived from the broader Lean philosophy and include:

Eliminate Waste: The first principle of Lean Testing is to eliminate waste, which refers to any activities that do not add value to the customer or the product. In software testing, waste could be unnecessary or redundant tests, or bureaucratic processes that slow down the testing process. Lean Testing uses the concept of "feedback" rather than "testing" and "improvement" instead of "correction" to enhance the product continuously.

Amplify Learning: The second principle encourages continuous learning and knowledge sharing within the team. For instance, when one software tester gains new insights, these should be shared with the entire team. Pair testing, where two testers work together on the same module, exemplifies this principle by facilitating early error detection and knowledge sharing.

Decide as Late as Possible: This principle advocates for keeping options open as long as feasible to make more informed decisions.

Deliver as Fast as Possible: Lean Testing streamlines processes to reduce the time from development to delivery.

Empower the Team: Team members are given the autonomy and tools they need to take ownership of the testing process.

Build Quality In: Quality assurance is integrated into every step of the development process, rather than being treated as a separate phase.

See the Whole: This principle focuses on the entire development process and how testing fits into the larger picture, rather than just individual components.

Benefits of Lean Testing

Lean Testing offers numerous benefits, including:

Efficiency: By eliminating unnecessary steps and focusing on value-adding activities, Lean Testing streamlines the testing process, leading to faster delivery times and lower costs

Quality Improvement: Lean Testing ensures high-quality software products by building quality from the start. Techniques such as pair programming, test-driven development, and pair testing are used to integrate quality into the process.

Continuous Improvement: A culture of continuous learning and improvement is fostered, allowing teams to enhance their processes and the quality of their products consistently.

Collaboration: Lean principles of learning and respect encourage collaboration and knowledge sharing. Teams are empowered to make decisions and work together in the decision-making process.

Customer Value: Lean Testing focuses on delivering value to the customer by eliminating waste and improving quality, ensuring that products meet customer needs and expectations.

Remember, The goal of Lean Testing is not just to test faster or cheaper but to make the testing process more effective and valuable. By adhering to these principles, teams can deliver high-quality software products that satisfy customer needs and expectations.

Cons of Lean Testing

While Lean Testing has many advantages, there are also potential drawbacks to consider:

Over-Reliance on Team Expertise: Lean Testing can be heavily dependent on the skills and expertise of the team, which can be a risk if the team lacks experience or knowledge in certain areas.

Resistance to Change: Organizations with established testing processes may face resistance when trying to implement Lean Testing principles.

Potential for Over-Flexibility: Too much flexibility can sometimes lead to a loss of focus or direction, making it difficult to maintain a clear vision for the product.

Challenges in Scaling: While Lean Testing can be highly effective for small teams, scaling the approach to larger organizations with complex structures can be challenging.

Conclusion

Lean Testing is a modern approach to software testing that emphasizes efficiency, quality, and team empowerment. By adopting Lean principles, testing teams can reduce waste, improve product quality, and deliver value to customers more quickly. However, it is important to be aware of the potential challenges and to implement Lean Testing in a way that aligns with the organization's goals and capabilities. With careful planning and execution, Lean Testing can be a powerful tool in the software development arsenal, ensuring that the product is not only delivered efficiently but also meets the highest quality standards.

A Feature which have become Bouquet of Bugs

Recently, I was testing an online shopping site – just for fun, nothing official. There I saw a feature called as “Tell A Friend”.  I found this feature useful in first glance. During shopping, if you see any product which you find usable for your friend and you think your friends might be interested, just forward info about the product in the mailbox of your friend. You just have to write name & email address of your friend. I think this is great idea to make new customers.

So, I thought to take my hands on this feature but I was highly disappointed when I used this feature. In hurry to introduce the new feature, the site managers kept a bouquet of bugs on the site. Let’s come with me to see the dissection of this feature with me.

Oh… I forgot to tell you the store name. It’s Zappos.com. First, some introduction with Zappos:

Zappos.com is an online shoe and clothing shop. Since its founding in 1999, Zappos has grown to be the largest online shoe store. Zappos did "almost nothing" in sales for 1999, but grossed over USD$800 million in merchandise sales in 2007 and grossed over $1 billion in 2009.

On Zappos.com I selected a product to see its description. The product seemed good to me and I was sure one of my friends would be interested in this product. I decided to forward the details of the product to my friend. So I clicked on “Tell A Friend” button available on the product page.

So I was on “Tell A Friend” Window.

After seeing this window I thought to play with this.

I clicked on Send button to see what would happen if values were not filled. On clicking send I saw two error messages. The error messages were:

• ·         You  didn’t specify an email to send to
• ·         You need to supply an email

Displaying an error message is not a formality. They could phrase the error messages in much better way.  Also they displayed the error messages in reverse order of the fields on the form. In the above screenshot you can see that the sender’s email address field appears before receiver’s email address. The error message should also display in the same order. This is not a rule but this is always expected.

From error messages it was clear that sender’s name is not mandatory here. Just one questions from all my readers – How many of you know email addresses of your all friends?

As a friend, I know all my friends by their name and not by their email addresses. So, I believe Sender’s name should be mandatory here.

After this I checked for the validations on the fields.

I filled numerals values in sender’s name, email and receiver’s email address fields.

Clicked on send button. The message had been sent.

As you can see there is no validation on sender’s name, email & receiver’s email address. The message had been sent. I didn’t know which poor devil was going to get this mail.

I have doubt that some professional developer has developed this window. It seems any school going kid has done the job. Even they are also aware of these validations.

Now let’s see the max length validation.

I used Perl Clip for generating the string of one million characters and pasted the string in each field.

No surprise, each field has accepted one million characters. Now I wanted to see what would happen if I click on Send button. So I did the job.

I had doubt that this message would ever go and guess what, I was right.

If they had put max length validation for each field, you have not to see this error. From here, I was sure that I was going to get many bugs in this feature.

This time I thought to select the checkbox to send a personalize message with the product details. So I clicked on check box. It displayed one more field along with Captcha verification.

I clicked on send button again without filling up any data in any field.

As you can see, It had given the same error messages. I was surprised why it didn’t show any error message for personalize message or Captcha. On looking down I saw that marked checkbox was unmarked. So you see on page refresh the data was lost.

Again, I filled up the complete form

and clicked Send button. See, what I got here.

 

Now, this was the biggest joke. The Captcha verification had been provided but application was unable to check the Captcha. Then, what it was doing here? Moreover, instead of fixing the error, the application was suggesting me to send the message without personalize message.

While sending the product details I wanted to tell my friend that why I have chosen this product for him but I couldn’t do that.

As application was unable to send a personalize message, it had also unmarked the checkbox itself, so I decided to send the product details without personalize message. I clicked on send button again.

What?????

It was still looking for Captcha.

To check behind the curtains I clicked on checkbox.

OMG!!!!

Text message was still there. Captcha also had been refreshed.  It means I couldn’t send product details until I remove the personalize message and Captcha text.

One funny thing I noted here: When Captcha text was incorrect, it has given the right error message but when correct Captcha text was entered earlier it was unable to process.

I was unable to understand whether they are making my job easy or tough. I could send direct mail to my friend much faster rather than using this add-on.

Next, I opened the “Tell A Friend” in Mozilla tab as you can see in the following image.

I wanted to see on clicking Cancel button whether it would close the single tab or all tabs. So I clicked on Cancel button. I was expecting tab to be closed but nothing happened.

So, I filled the data in the field and click on Send button. The message was sent.

I clicked on Close button but as usual nothing happened.

Finally I decided to close the window myself and never tried to open it again. I was frightened with “Tell A Friend”.

Before finishing, I just have one request – Just try to reduce the tasks of a user instead of multiplying them. They have lots of things to do in life. Before releasing, please make it sure that application doesn’t have such kinds of stupid bugs.

I am an Impersonator

I am a tester for some time now. A tester plays different roles for his job so do I and believe me I am happy about that. It seems that I am living life of an Impersonator. Some of you might be thinking what is an Impersonator?

An impersonator is someone who imitates or copies the behavior or actions of another.

Now when you know what is impersonator, you must be thinking why I am so happy about it? Actually I don’t think that any other career than testing can give me opportunity to play such different roles and this is not an exaggeration. When an actor can proud on his different characters played in different movies then why can’t I.

Different roles which I play

I am an Advisor: An Advisor is normally a person with more and deeper knowledge in a specific area i.e. a specialist. As a tester I generally play the role of an advisor. I give them suggestions from my experience with different products during development, I suggest them how they can make software better. I suggest them during bug fixing. Even I suggest them how to display an error message. What if they don’t follow every time what I suggested, sometimes even they don’t consider it but they always know I am doing best to help them and they are always keen to know my thoughts. That is sufficient for me.

I am a Police Officer: A Police officer is generally charged with the apprehension of criminals and the prevention and detection of crime, and the maintenance of public order
In Beautiful Testing, Linda Wilkinson has said:

Are testers policemen? Not usually. They can’t “arrest” anyone for breaking a law, even if the world of software development could figure out what those laws should be, and most do not have the authority to keep something from moving to production, regardless of the generic goodness (or badness) of the software.

According to me, a tester also wears a cap of a policeman. As a policeman, I find the culprit who breaks the laws of an application and put it behind the bar. The culprit in this case is a bug. I find the bug and log it in the bug sheet.

I am a Detective: A detective is any licensed or unlicensed person who solves crimes, including historical crimes, or looks into records. My job allows me to play the role of a detective.
For being a good tester, it is important to have good detective skills. A good tester is not who finds an issue, a good tester finds the issue and the reason behind that issue and here I need my Detective Skills to find the reason behind any issue. Sometimes I fail to find the reason but I always try. It helps me to know the product better than anyone else.

I am a Lawyer: A lawyer is a person who is learned in law and licensed to practice the law. As a detective I found the evidences and found the culprit, as a policeman I have put the culprit behind the bars but what if the culprit is escaped due to poor advocacy. To win a case we need strong prosecution against the culprit otherwise the defense lawyer can make him free. Similarly, sometimes we need strong prosecution skills against a bug. I need to describe the impact of the bug to the developer. In Software Testing it is called as Bug Advocacy.

I am a Critic: A critic is a person who offers reasoned judgment or analysis, value judgment, interpretation, or observation. Like a critic, I analyze a product according to my knowledge and share my views with the stakeholders about the product. I don't bother about what they want to hear actually, I just give them an honest opinion.

I am an End User: An end-user as the person who uses a product. This is the most important role which I play. It is an end user who is going to use the product finally so it is important to understand an end user for the success of the product. I test any product with the perspective of an end user and discuss my views with the development team and other stack holders so that they can improve the product accordingly.

I am a Reporter: A reporter is a type of journalist who researches and presents information in certain types of mass media.
Any news is breaking news if it is most significant story of the moment. It could be a story that is simply of wide interest to viewers and has little impact. As a reporter, I report the entire bug with all the evidences as soon as I find them. Late reporting can cause benefit to other reporters. Once an issue is found, I immediately report it.

I am a Salesman: A Salesman represents a person or company on the selling end of the deal. A real Salesman is that who sells the product to a customer when he needed it least. Sometimes I need to sell the bugs. I have found the bug, I have reported about it, On the basis of my bug advocacy it is also proved that the bug is critical and must be fixed but still I need to make the developers to fix it in current release. In that case, I use my Salesman skill to convince them to fix the bug immediately. It’s like selling a bug.

I am a Tester: and in the last but above all I am a tester. I need to change my role according to the situations but it is only because of the need of my Job. My basic job is to test the product. It is versatility of my job which allows me to wear the different caps at different time.

Am I missing any role? I might be....do tell me....... :)

Bulls and Cows

There is an old proverb - Necessity is the mother of invention. When a scientist invents something there is always a need. The Need is the final motive of any invention.

What is Need?
Need is a condition or situation in which something is required. In short need is requirement.

But what if the need is wrongly interpreted, Is the invention possible in that case? Might be possible but it would not be right invention; it would not actually do what we needed.

Now we change the above proverb according to IT Industries.

Requirement is the mother of every product.

Now what if requirement is wrongly interpreted, is the product possible in that case? Might be possible but it would not be right product because it would not do actually what stakeholders needed.

To provide a quality product to client, it is very important to understand the needs of the client. The purpose of testing can't be fulfilled if tester doesn't understand the requirement properly.

Why the requirement is mis-interpreted?
There may be various reasons such as:
• The clients/ users actually don’t know themselves what they really want or what they need?
• When it is impossible to know who yours users will be and it is quite often if we don’t consider the narrowly defined situation such as an EHR application.
• In general Requirements are not detailed enough to understand the exact needs of the stakeholders.

How the situation can be avoided?
The best solution is questioning. Questioning can be used as a tool to understand the exact requirement of a client. More you ask questions, more you clear about the product.

To depict the power of questioning and how it helps to understand the requirements of a client, we can take example of a game called “Bulls and Cows”

What is Bulls & Cows? - In childhood, you might play this game. This is also known as Cows and Bulls or Pigs and Bulls or Bulls and Cleots. This is a code breaking game played between two players.

How the Game is played? - On a sheet of paper, one player writes a 4-digit secret number. The digits must be all different. Then, the second player tries to guess this number. If the matching digits are on their right positions, they are "bulls", if on different positions, they are "cows". Example:

Secret number: 9374
Opponent's try: 4873 and asks “Is this correct?”
Answer: 1 bull and 2 cows. (The bull is "7"; the cows are "3" and "4".)

On the basis of answer, the opponent tries again until he finds the secret number. By asking a single Question again and again, Opponents finds the correct number.

When a single question can help to find a number then imagine how many questions you can ask in a requirements document. Asking Questions is a skill and it comes with lots of practice and time. But if you know the skill of questioning, there is no way to mis-interpret the requirements.

My Suggestion: If you find problems to understand the requirements then you should practice “Bulls & Cows”. If there is nobody to play with you, don't panic we have an open source version of “Bulls” and “Cows” called 4 digits.
The game's objective is to guess a four-digit number in 8 times using as less time as possible.

Chapter 2 - Kids can do Boundary Value Analysis!!

My niece is 5 years old. She doesn't know what is software testing, in fact she doesn't know what is software but still she can do Boundary Value Analysis. Amazing na.... although I have never asked her to do so but still I am sure that she can do it.

Surely, you will be surprised how I am so sure? Actually, she can add the numbers, subtract the numbers and that is exactly what most of us do on the name of Boundary Value Analysis.

I was also following the same approach until Pradeep Sir has not mentioned it in one of his workshop. The question is - Are we really doing analysis?

The Wikipedia says:
Analysis is the process of breaking a complex topic or substance into smaller parts to gain a better understanding of it.

As definition says Analysis is just not adding or subtracting 1. It seems that we have changed the definition of analysis. If what we are doing is analysis then perhaps the software testers at NASA are doing the same :) They are just adding and subtracting the numbers. If that so, any body who can do addition and subtraction can join panel of Software Testers in NASA.

Boundary value analysis is a software testing design technique in which tests are designed to include representatives of boundary values. Values on the edge of an equivalence partition or at the smallest value on either side of an edge. The values could be either input or output ranges of a software component.

The definition doesn't mention +1/-1 approach. It also doesn't tell us that BVA can be be applied on input fields only which we generally do.

It is said that most of the bugs reside on the boundaries. Don't know who made this statement. Might be a tester has made the statement when he found most of the bugs at the boundaries when he was testing an application.

But is he right?

Might be he is right but did he really applied the +1/-1 approach. I don't think so. Check out the total bugs logged by you and then see how many bugs you have found by +1/-1 approach. I am sure the percentage would be very low.

Perhaps we are misunderstanding the concept of Boundary Value Analysis or Might be we need to rename the +1/-1 approach. How about calling it “Kids Approach”.

Think about it tell then let me try to find out what is Boundary Value Analysis?

Lessons Learned from Pradeep Soundararajan

Chapter 1 - A Great Learning Opportunity

It was just like an ordinary day. I am working in the office doing tests, having discussions with developers & meetings etc. I was not on my desk for last two hours due to such a meeting. When I returned back I saw a message from Pradeep Sir. I was little bit amazed as I don't receive messages from him regularly so i pinged him back immediately and what he said has changed the ordinary day into special one.


Pradeep Sir was coming to Noida for a corporate workshop and he offered me to attend the workshop for free (not completely free). I was more than happy but two question were in my mind :) (Question should always be there :))

1. Why Pradeep Sir has offered me to attend his workshop on less amount?

2. What would I need to pay to attend the workshop?


But next day I got the reply of my each question.


I don't remember the exact wordings which he used but they are some thing like : Mohit, money is not a big thing. I have sufficient money, so you need not pay anything. Last time you have paid from your own pockets to attend my workshop so this is your reward from me. What I really want from you to learn, learn and learn more and try to help the testing community from your learning and this would be your fee.


I promised him to do so but couldn't do anything yet what I have promised. If I have done so then you would definitely read this article at least 15 days ago but I hope Pradeep Sir know what were the reasons for being late.


Anyway, the two days workshop from Pradeep Sir was one of the best experience.


Don't know what is best... Attending the workshop on Exploratory Testing from the country's best Exploratory Tester, Watching him doing testing, Having discussion with him over lunch or having a vodka shot after the workshop.


The workshop has started with the introduction of Pradeep Sir and ends with SBTM (Session based Test Management). In between we have spent 17 hrs learning the testing skills from one of India's best tester.


Only one blog post can not comprise the whole learning session and it would not be justified to do so I am going to post them in parts one by one. Wait for my next blog post which will discuss “Kids can do Boundary Value Analysis!!”.
